BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall fixing structure for an intake / exhaust type heater.

[0002]

2. Description of the Related Art An intake pipe and an exhaust pipe attached to the back of a frame are connected to intake and exhaust pipes, combustion air is taken in from outside, and burned by a burner in the frame, and high-temperature combustion gas generated by the burner is exchanged with heat. In an air-intake / exhaust-type heater that exchanges heat with room air by means of a vessel and discharges exhaust gas at a low temperature to the outside of the room, it is necessary to fix the intake / exhaust tube to a wall and the heater body to a floor or a wall.

As a conventional fixing method, a fixing plate is provided at a rear portion of a frame, a mounting plate is disposed between the frame and the wall, and both ends of the mounting plate are fixed to the fixing plate and the wall with screws. To fix the frame to the wall. At this time, if the mounting hole of the mounting plate with the fixing plate is formed by a long hole, the frame is moved back and forth after the mounting plate is fixed to the wall, and the screw between the long hole of the mounting plate and the fixing plate is tightened. By changing the position, the fixing position of the frame can be adjusted.

[0004] Further, there is a type in which a back cover is attached in place of the fixing plate. A slit for ventilation is provided in the back cover arranged so as to surround the convection blower, and the attachment plate and the back cover are interposed through the slit. At this time, the fixing position of the frame can be adjusted by changing the screw tightening position between the mounting plate and the slit.

[0005]

When the fixing position of the frame is adjusted as described above, the adjustment range is determined by the length of the long hole or slit. The adjustment range can be widened, but the fixing plate and the back cover must be greatly projected to the rear of the frame in accordance with the length of the long hole or slit.

The gap between the frame and the wall is determined by the size of the air intake / exhaust tube and the convection blower disposed at the rear of the frame, but only by the fixed plate and the rear cover protruding at the rear of the frame. It took extra installation space and wasted space when the heater was mounted on the wall.

On the other hand, in order to narrow the gap between the frame and the wall by suppressing the projection of the frame of the intake / exhaust tube or the convection blower to the rear, the dimensions of the fixing plate and the back cover must be reduced. Since the holes and slits are shortened according to the fixing plate and the back cover, the adjustment range of the frame is narrow, so the work must be done with the frame close to the wall, and the heater must be installed. It will be difficult.

Further, attaching a fixing plate or a back cover to fix the heater to the wall increases the number of components, necessitates a process for each component, and may lead to an increase in cost.

In addition, in the intake / exhaust type heater, it is necessary to fix the frame 1 to the wall A or the floor in order to prevent the piping of the intake / exhaust device from coming off or falling down. 5 is a mounting plate for fixing the frame 1 to the wall A, 6
Is a fixing plate attached to the rear part of the frame 1, 7 is a screw for fixing the mounting plate 5 and the fixing plate 6, and 7a is a screw for fixing the mounting plate 5 to the wall A.

The installation of the intake / exhaust type heater requires the intake / exhaust tube 4 to be mounted on the wall A.
After connecting the intake pipe 2 and the exhaust pipe 3 attached to the frame 1 to the intake / exhaust tube 4, the mounting plate 5 and the fixing plate 6 are fixed with screws 7, and the mounting plate 5 is fixed to the wall. The frame 1 is fixed to the wall A when it is fixed to A with the screw 7a.

Reference numeral 5a denotes a long hole 5a which forms a screw hole with the fixing plate 6 of the mounting plate 5. After the mounting plate 5 is fixed to the wall A, the frame 1 is moved back and forth to form the long hole 5a. By changing the fastening position with the fixing plate 6, the fixing position of the frame 1 can be adjusted. At this time, the length of the fixing plate 6 is set so as to correspond to the long hole 5 a, so that the end of the mounting plate 5 does not hit the rear surface of the frame 1 when the frame 1 approaches the wall A.

On the other hand, in another conventional example shown in FIG.
